MOSCOW, May 26 (Xinhua) -- Russia believes that a new UN resolution on the Democratic People's Republic of Korea (DPRK) should not impose an international isolation or blockade on the country, the Itar-Tass news agency reported Tuesday, citing a source with the Russian Foreign Ministry.

    "In any case it is counterproductive to raise the question of the DPRK's international isolation. The path to dialogue should not be disrupted, and the problem can be solved only in political and diplomatic ways," an unidentified official was quoted as saying by Itar-Tass.

    "The reaction must be sufficiently serious because the authority of the Security Council is at stake," said the diplomat.

    On the one hand, the reaction should be clear enough, on the other, it should not envision an international isolation or blockade, he said.

    The DPRK claimed to have successfully conducted an underground nuclear test on Monday, which triggered strong condemnation worldwide.

    The UN Security Council on Monday denounced the nuclear test as a "clear violation" of existing council resolutions and said it would seek a new resolution immediately.
